PAPER-ROLL ABUTTER.

To all 107mm it may concern Be it known that T, CHARLIE EDWIN TE-EH8, acitizen of the United States, residing at Oakland, in the county ofAlameda and State of California, have invented new and usefulImprovements in Paper-Roll Abutters, of which the following is aspecification.

his invention relates to improvements in holders for rolls of paper suchas are used for wrapping paper, toilet paper and the like.

The obj ectof the invention is to provide an attachment for paper rollholders for automatically projecting the end of the roll of paper afterthe desired amount has been torn off to provide for the ready grippingof the paper by one end when another supply is required.

' With this and other objects in view, the invention consists of certainnovel features of construction, and the combination and arrangement ofparts as will be more fully described and claimed.

In the accompanying drawings: Figure l is an end elevation of a rollholder equipped with this attachment and with the attachment in raisedposition. Fig. 2 is a similar view with parts broken out and with theattachment in lowered position-which it assumes wien the paper is beingunwound from the roll. Fig. 3 is a front elevation thereof. Fig. 4 is atransverse section thereof. Fig. is a detail plan view of one end of thefeeding rolls. 6 is a detail view of one of the rollers.

This attachment may be applied to any roll holder and in the embodimentillustrated is shown mounted on a stand comprising a base A. havingspaced uprights B and C connected at their upper ends by a cross bar D.A shaft E is revolubly mounted in the uprights B and C and on which apaper web F is wound. This improved attachment as shown comprises aframe composed of two arms 1 and 2 pivotally mounted at one end on studs3 which project from the outer face of the uprights B and G, preferablybelow the shaft E. The other ends of these arms 1 and 9 are connected bya paper feeding and severing device in the form of upper jaws a andlower jaws 5 hingedly connected at one end as shown in Fig. 8 to providefor the placing of the paper web as is Specification of Letters Patent.

shown clearly in Fig. 2. These jaws have longitudinally extending upperand lower cutting blades 4t and 5 for severing the paper web at thispoint, the upper blade being shown hollow ground and the lower ground atright angles.

Two rollers 6 and 7 are revolubly mounted in suitable hearings, in theaws t and 5 and are designed for feeding the paper web F between them.These rollers are arranged in close proximity to each other as shown inFig. :2, being spaced apart sufiiciently to permit the paper web F topass between them and be fed thereby on a forward pull being exerted onsaid web. A spring catch 12 re liably connects the jaws 4t and 5 attheir free ends to hold the rollers in operative position. The upperjaws 4t have transverse slots 13 therein in which the spindle ends ofthe upper roller 6 are mounted to adapt said roller to move laterallyrelative to the roller 7 to provide for variation in thickness of thepaper used. Plate springs 14 are m0unted to bear on said spindle ends tohold the roller 6 in yieldable engagement with the roller 7.

The upper roller 6 has a peripheral recess 8 formed in one end thereofand extending around the entire circumference to receive a flexibleelement 9 which is adapted to be wound on said roller. This element 9 ishere shown in the form of a cord secured at one end. to the cross bar Dof the holder and at its other end in the recess 8 of the roller 6. Inthe other end of the roller 6 is mounted a spring ccmrolled shaft 10which projects beyond the end of the roller and forms a journal for thisend of the roller. A coiled spring 11 encircles said shaft 10 and issecured atone end to said shaft and at its other end to the roller as isshown clearly in Fig. 6. The turning of the roller 6 in one directionwill wind up the spring 11 and unwind the cord 9 from the roller whichoccurs when a pulling tension is exerted on the paper web F and whensaid web is released or torn ofi' the spring will uncoil and therebyfeed the web forward a short distance and at the same time will wind upthe cord 9 on the roller 6 and raise the attachment into the positionshown in Fig. 1 leaving the end of the web projecting a suiiicientdistance to be readily gripped when a further supply of paper isdesired.

lVhile l have described my invention with more or less minutencss asregards details and as being embodied in certain precise forms, I do notdesire to be limited there-to unduly any more than is pointed out in theclaims. On the contrary, I contemplate all proper changes in form,construction and arrangement, the omission of immaterial elements andsubstitution of equivalents as circumstances may suggest or render e2;-pedient.

1 claim as my invention:

1. The combination of a. pivoted turnable roll holder, arms pivoted outof line with the roll holder axis, feed rolls upon the outer ends ofsaid. arms, one of said rolls containing a torsional. spring, a cordcoiled around said feed roll and having its other end fixed, said cordwinding upon the feed roll and advancing the paper when the feed rollholder is raised about its pivots.

2. The combination with a paper roll holder and its journal. support, ofarms journaled out of the axial line of the holder, feed rolls andcutters mounted upon the outer end of the arms and between which thepaper is at vanced, a cord fixed at one end and having the opposite endcoiled around one of the feed rolls, a torsional spring within said rolladapted to wind the cord and advance the paper as the arms are moved upand dow about their pivot.

3. The combination with a paper roll support, of a frame pivotallymounted on said support, feed rollers mounted in said frame, a cutterdisposed in advance of said rollers, a flexible element connected at oneend to one of said rollers and at its other end to said roll support,and a spring carried by said roller for winding up said flexible elementwhen the roller is turned in one direction.

a. it feeding attachment for paper roll holders comprising a framehaving revolubl mounted rollers arranged therein and disposed adjacentto each other, a cutter arranged in advance of said rollers one of saidrollers luring a recess in one end, a shaft rcvolubly mounted in saidrecess and projecting beyond said roller to form a journal for one endthereof, and a coiled spring wound on said shaft and connected at oneend thereto and at its other end to said roller.

A feeding attachment for paper roll holders comprising a frame havingrevolubly mounted rollers arranged therein and disposed adjacent to eachother, severing means arranged in advance of said rollers one of saidrollers having a. recess in one end, a shaft revolubl mounted in saidrecess and projecting beyond said roller to form a journal for one endthereof, and a coiled spring wound on said shaft and connected at oneend thereto and at its other end to said roller, the other end of saidroller having an annular recess therein, and a flexible element securedat one end to said recessed endv of said. roller and adapted to beconnected at its other end to a. lixee support.
